Hi Doron,
KSM is controlled by MoM, which gets its policy from the engine through VDSM. MoM will call ksm directly as needed when needed. If you choose to disable it the policy needs to get updated. Can you please check your mom logs and see if there are any errors there? I wasn't aware of mom.log, thanks! :-) After another host reboot and a manual "Sync MOM Policy" it seems like the setting finally came

Now the ksmd process is still there, but it remains idle.
Indeed ksmd process will always be there. The ultimate place to check whether it's working or not is /sys/kernel/mm/ksm/run file. "1" for running and "0" for sleeping. mom.log is reflecting its value and MoM process will change it as needed.
I've tried this multiple times before upgrading to 3.5.0 GA today. Maybe it was broken between RC and GA.
I'll keep an eye on this and open a BZ in case the setting will change again.
